ALTELYS Input data

Description

The data used is by nature multiple and heterogeneous in terms of its types and sources. It is made up of satellite images, vector data and tabular data.   

Satellite data

Satellite imagery will be used to characterize surfaces (buildings, vegetation, phenology) at high resolution, as well as their thermal behavior (infrared), and then to generalize climate information (UHI) to the whole of the country. The developments made will be compatible with the next TRISHNA mission.

• Optical data (visible and near infrared):
  • Landsat 8 and 9
  • Aster
  • Sentinel-2: land use
  • Sentinel-3: Surface temperatures
  • Pleiades: land use, DSM, DTM, DHM
• Infrared (thermal) data:
  • Landsat 8 and 9
  • Aster
  • Ecostress (subject to availability/compatibility)
  • Some of this data will be taken (subject to compatibility) from previous SCO projects, in particular THERMOCITY, SAT4BDNB.

Other

• IoT sensor network (indoor / outdoor):
  • LoRaWan (sensors from the Rennes Urban Network, France)
  • NetAtmo (citizen sensors to be deployed in Brazil).
• Matrix data:
  • IGN HD LIDAR
  • Pleiades DSM
  • Copernicus "large scale" (temperature, relative humidity)
  • Surface temperature by month / department
• Vector data :
  • IGN Database topo /parcel - OpenStreetMap
  • BDNB (National Building Database)
  • BDD DPE (Database of Energy Performance Diagnostics)
